Application filed May 28, 1906. Serial No. 319.188.

To a/ZZ whom it may concern:

Be it known that I, HENRY THURsToN HUDSON, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in plows and the like, andmore particularly to a power-operated machine of this character which employs a revolving shaft carrying earth-working disks.

One object of the invention is to provide a simple and practical rotary disk plow of this character in which all the parts will be supported upon the wheels of the traction-engine or motor which propels and operates it.

Another object of the invention is to provide a machine of this character with an improved means for raising and lowering the earth-working disks.

A further obj ect of the invention is to improve and simplify the construction and operation of machines of this character, and thereby render the same more durable and eflicient and less expensive.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of my improved steam-plow. Fig. 2 is a plan view of the same with parts broken away to more clearly illustrate the construction. Fig. 3 is a detail transverse view, partly in elevation and partly in section, showing the manner in which the earthworking disks or plow proper is adjusted or raised and lowered and Figs. 4 and 5 are detail views.

Referring to the drawings by numeral, 1 denotes a traction-engine of the usual horizontal-boiler type, mounted upon front supporting and steering wheels 2 and rear supporting and propelling wheels 3 and having mounted upon its rear portion a supportingframe 4, which comprises suitably-connected side beams 5, hung by means of bearings 6 from the axle or shaft 7 of the tractionwheels 3. Mounted upon the top of the engine-frame 4 and above the rear of the boiler is a c'ab 8 for the operator and within which are located the various levers and devices for controlling the different parts of the mae chine. Mounted upon the top of the forward portion of the boiler is a steam-engine 9, the fly-wheel shaft 10 of which is suitably geared to the traction-wheels 3, so that the machine may be propelled in the usual manner.

Disposed in rear of the traction-engine is the plow proper, 11, which consists of a plurality of concave earth-working disks 12, rotatably mounted upon the arms 13 of heads or spiders 14. The latter are secured at suitable intervals along a horizontally disposed and transversely-extending shaft 15, which has its outer ends j ournaled in bearings upon the lower ends of hangers or brackets 16 which latter have their upper ends secured to the rear of a vertically-swinging frame 17 This plow-frame 17 is in the form of a lever, which is fulcrumed intermediate its ends and carries the plow or earth-working element 11 upon its rear end or portion and suitable counterbalancing-weights 18 upon its front or forward portion. The swinging frame or lever 17 is composed of two side members, connected at their rear by cross-bars 19 and each comprising a rearwardly-projecting beam 20 and a forwardly-projecting beam 21. These beams are angularly disposed with respect to each other and have their inner ends connected together, as shown, and to a bearing 22, which engages a pivot or ful crum 23, the latter being provided upon the rear portion of the engine-frame 4. The beams 20 21 are further connected by trussrods 24, and braces 25 are provided between the brackets or hangers 16 and the rear ends of the beams or bars 20, which latter have the cross-bars 19 connected to them.

The plow proper, 11, is adjusted vertically to vary the depth of the cut made by the earth-working disks 12 or to support the same above the ground when not in use by p swinging the frame or lever 17. This is preferably accomplished by rotating a handwheel 26, located within the cab 8 and fixed upon the rear end of a longitudinally-extending operating-rod 27, upon the forward end of which is provided a worm 2S. The latter meshes with a worm-gear 29 upon the upper end of a vertically-extending shaft 30, suitably mounted in the engine-frame 4. Wound in opposite directions upon the lower end of this shaft or upon a suitable drum provided thereon are the inner ends of cables or other flexible connections 31, which extend from said shaft transversely in opposite directions and pass around guide-pulleys 32 upon the outer sides of the frame 4. From the pulleys 32 the cables extend upwardly and over similar guide-pulleys 33, mounted upon the forward ends of the bars or beams 21, and from the pulleys 33 they extend downwardly and have their ends xedly attached to the frame 4, as at 34. It will be seen that by rotating the rod 27 the worm-gearing will turn the winding-shaft 30, so that the cable will be either wound upon or unwound from its lower end for the purpose of raising or lowering the forward end of the frame or lever 7, and hence swinging its rear end, which latter carries the plow 11. The provision of the counterbalancing-weights 18 upon the beams 20 permit the hand-wheel 26 to be readily turned.

In order to hold the plow-frame or lever 17 in an adjusted position, so as to take the strain off -of the cables 32, either after the plow has been adjusted to cut the desired depth or after it has been elevated to an inoperative position, I provide upon each side of the machine a chain or other fiexible connection 35, which has its lower end secured to the engine-frame 4 and its upper end detachably engaged with a hook 36 upon the front end of one of the beams 21. These chains 35 will support the weight of the plow and the rear of the lever or frame 17, and thus remove all strain from the cables.

The shaft 15 of the plow has upon one of its ends a sprocket-wheel 37, which is driven, by means of a sprocket-chain 38, from a sprocket-wheel 39 upon the outer end of a transversely-extending shaft 40. This shaft is mounted in suitable bearings upon the engine-frame 4 and has upon its inner end a pinion 41. The latter is keyed to rotate, but is slidable u on the shaft 40 and meshes with a gear 42, w ich latter in turn meshes with a gear 43, provided upon the shaft 7. By means of this gearing the power is transmitted from the engine to the plow-shaft 37, so

that said shaft will be rotated as the machine is moved forwardly.

In order to throw the plow-shaft out of operation, a shipper-lever 44 is provided for shifting the pinion 41 out of mesh with the gear 42. j

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined by the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl 1. rI`he combination with a traction-engine, of a tilting frame or lever pivotally mounted intermediate its ends upon said engine, a rotary shaft carried by the rear end of said lever, earth-working disks upon said shaft, means for driving said shaft, a counterbalancing-weight upon the forward end of said lever, a windlass for adjusting the forward end of said lever, and an adjustable flexible connection between said engine and the forward end of said lever.

2. The combination with a traction-engine, of a tilting frame or lever consisting of side portions connected by a rear portion, pivots upon said engine, bearings upon the side portions of said lever engaged with said pivot, a shaft hung from'the rear portion of said lever, arms radiating from said shaft, earth-working disks upon said arms, means for rotating said shaft, counterbalancingweights upon the forward ends of the side portions of said lever, a winding-shaft, cables wound upon said shaft and attached to the forward ends of the side portions of said lever, guides for said cables, an operatingrod, worm-gearing between said rod and said winding-shaft, and flexible connections between said engine and the forward ends of the side 'portions of said lever, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- MAUDE REILLY.
